And, I can state without a doubt, the speedo drive gearing differs between the manual and automatic transmissions. I don't know about all manual transmissions but, the speedo outputs on the old cast iron 4-speed I had and, the Getrag 5-speed that's in the car now are both the same.

a few things.
first the na 300ds have 346 gears, the 240 123 has 369 gears.
second, the output on the speedo is off the tail shaft of the tranny so if the torque converter is slipping it does not know anything about it so the speedo has no need of a different gearing.
you should always get better economy with a stick all other things being equal, less slip and it takes less power to twist a manual tranny than an automatic (these old ones anyway).
Glad you are enjoying your manual conversion. I am too.
